I too have the same exact problem as the first poster in this thread.
I obtained Freespace 2 from macgamefiles.com
downloaded the newest version of FS2_Open (3.6.9 Final) from macupdate, and ran the program.
I also have the newest version (3.0.1) of the FS_launcher
i tried to install some of the updated graphics files, but no documentation was included with them, so i am really not sure if i installed them correctly. (this applies to the rest of the media files on here as well. i dont know if i should put them in the directory with the FS2_Open executable, or in the data folder, or what) also, i am not sure how to set any of these flags in the command line. when i launch the program, it just launches, no command line is there.
lastly, i tried d/ling the install of FS2 using the FreespaceOpenInstaller jar container. i had the same problem. please, i just need a little explanation on how to use these "mp-710_adveffects.vp" files and if i should be using a different installer or what. also, on that note, FS2_Open worked fine for me under tiger, but leo has all these graphics problems >_< (oh yeah, im running FS2_Open using 1024x768 @ 32 bits )
